If this is a loss, a loss compared to what? Centralised servers? If Lemmy was a centralised server, this would’ve taken the whole site down. As another commenter mentioned, if the US government decides take Reddit down, the whole service would be lost. But in the Fediverse no single government can stop it.
Another example is when lemmy.world was attacked. All other instances and the custom clients continued to work. If you say this is a bad look, what’s a good look in your opinion? All of Lemmy going down at the same time? If centralised services deploy techniques to keep their services stable (horizontal scaling, regional mirrors etc.), Fediverse apps can use all of those techniques plus then some.
